HEATING SYSTEM.

Application filed m 12, 1920. Serial 110. 880,781.

, to be a full, clear, and exact desoriptionof the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tocharacters of reference marked thereon, which form a part of thisspecification.

This invention relates, generally, to improvements in heating systemsfor buildings, etc.; and the resent invention has reference,

more particu arly, to a novel heating system in which is employed one ormore gasheaters in which water is heated, so as to produce vapor, whichvapor is drawn by 7 means of a circulating pump, or similar means, afterthe circulating pump has started, through a system of piping and aradiator or radiators located in said piping, the system comprising alsoa motor-driven or otherwise suitably operated blower for forcing asupply of air to the gas-burner produced in a usual hot-water such as isordinarily used in dwe hugs, the

or burners of the gas-heater or heaters above mentioned.

The present invention, therefore, has for its principal object toprovide a noveland simple heating system in which va or is aseater,

gas-heater being installed in the circulating pipes of the heatingsystem, and in which a constant circulation of vapor is maintained at avery slight expense and at a great saving of fuel, the devices and partsof the system being arranged to operate in a rapid and efiicient manner,as soon as the gas is lighted, so that immediately upon the openingofthe radiator-valve an immediate and rapid circulation of hot vapor willbe produced through the pipe-system and the radiator or radiatorslocated in said system.

Otherobjects of the present invention not at this time more particularlyenumerated will be clearly understood from the follow ing detaileddescription With; the various ob ects of the present invention in view,the said invention consists, primarily, in the novel heating systemhereinafter set forth; and the said invention consists, furthermore, inthe novel arrangements and combinations of the various devices andinstrumentalities comprising and embodying the novel features of thepresent invention, as well as it. the details of the construction of theseveral parts, all of which will be more fully described in thefollowing specification, and then finally embodied in the clauses of theclaim which are appended to and which form an essential part of the saidspecification.

The invention is diagrammatically illustrated in the accompanyindrawing, which shows one embodiment o vention.

In the said illustration, the referencecharacter 1 indicates a suitablestorage tank, adapted to be supplied with water from the usualwater-supply pipe 2, in whichthere may be a shut-ofi' cock, as 3. Thispipe 2, as shown, leads into the top or upper portion of said tank, andconnected with and extending from the bottom or lower portion of thetank1 is a water-conveying pipe 4, connected with and leading into the sideand near the bottom of an ordinary waterheater or heaters, as 5,of theusual household type. Within the Water-heater 5 is a coil, as 6,terminating in the side, at or near the upper portion of the heater.Connected with the upper portion of the coil or coils 6, as the case maybe, is a main pipe 7 and its branches, as 8, in which are arranged theradiators 11 of any suitable and usual construction. The pipes 7 and 8may be provided with the usual shut-off valves, as 9 and 10,substantially as shown.

The reference-character 12 indicates a return-pipe of the main system,and 13 are return-pipes from the radiators to said main return-pipe 12,said return-pipe 12 being connected with the water-conveying pipe 4which is connected with the heater or heaters 5.

In connection with the above described system is employed a suitablearrangement of. circulating blower or pump 14, and an air-blower 15, allpreferably arranged upon a single shaft 16, upon which is also mountedan electric motor 17, or other suitable prime mover, for operating saidshaft 16, the circulating pump 14, located above the normal water-levelin the tank 1, and the air-blower 15 mounted upon said shaft. The bloweror pump 14 is connected with the main return-pipe 12 by means of a pipe18 which leads from the return-pipe 12 into the inthe present intakeside of the blower or pump 14, and connecting the discharge end of thesaid blower or pump with .the storage tank 1. is

a pipe 19. .[he previously mentioned heaters 5 may also be connectedwith the pipe 19 by means of connecting pipes 20 which lead into theupper end-portions of the said water heaters 5, said pipes 20 beingpreferably provided with suitable shut-off valves, as 21. The said pipes18, 19 and 20, as will be evident are also located above the normalwater-level in the tank 1. Connected with the exhaust or outlet-end ofthe air-blower 15 is a pipe 22 which leads to the burner or burners 23of the heater or heaters 5 for forcing air from the blower to saidburner or burners to create an increased amount of heat, as will beclearly evident from an inspection of the drawing. The pipe 22 isrovided with the usual stopcocks 24, an 25 is the usual gas-supply pipein which the burner or burners 23 are arranged, suitable stop-cocks 26being also placed in the pipe 25.

From the foregoing description it will be clearly evident, t at a Simpleand efiiciently operatin heating system, in which heat is produce byvapor is the result, said system being es ecially adapted for use inconnection wit hot-water heaters or boilers of the usual type ordinarilyused in dwellings.

From an inspection of the drawing it will be noticed that thelight-pressure blower or pum 14, with its plpes 18 and 19, is 10- cateat a point above the normal level .r-w of the water within the tank 1,the result bein that when either or both of the burners 23 ave beenlighted, and the prime mover 17 has been set in motion, any air andwater due to condensation, that may be contained in the radiator orradiators, is drawn therefrom into and through the pipes 13 and 12, anycondensed water dropping past the pipe 18 into the lower portion of thepipe 12, While the air is drawn into and through the blower or pump 14,forced into the pipe 19, and thence into the upper portion of the tank1, above the level of the water therein, and also into the upper por-'tion of the heater or heaters 5, for equalizing purposes, to revent avacuum both in the tank and the eaters, where this portion of the air isheated and passes through the pipes 7 and 8, co-mingled with the heatedvapor from the coils 6, back into the radiator or radiators.

Owing to the light pressure of the blower or pump 14, and due to thefactthat it is located considerably above the level of the water withinthe tank 1, any tendency of short-circuiting the water through the pipe19, the tank 1, the ipe 4 and the lower part of the pipe 12 to t eblower or pump is entirely overcome.

I am aware that some changes may be made in the general arrangements andcombinations of the various devices and parts, as well as in the detailsof the construction of the said parts, without departing from the scopeof the present invention as set forth in the foregoing specification,and as defined in the clauses of the claim which are appended thereto.Hence, I do not limit my present invention to the exact arrangements andcombinations of the several devices and parts as described in the saidspecification, nor do I confine myself to the exact details of theconstruction of the said parts, as illustrated in the accompanyingdrawing.
